Title: Scene change detector for digital video
Inventor: CHEN XUEMIN
IPC: H04N7/26
Filed: 1997-09-25
Granted: 1999-06-11
Abstract: In a method for detecting a scene change between a prior video picture and a current video picture of a sequence of pictures, an average luminance value is determined for a block pair of the prior and current video pictures. Preferably, the blocks of the block pair are located, respectively, in the same relative position in the prior and current pictures. An incremental visual sensation value is determined using a difference between the average luminance values. If the incremental visual sensation value exceeds a block contrast threshold level, a scene change is indicated. In particular, if the minimum of the average luminance values of the current and prior picture blocks exceeds a dark scene threshold, the incremental visual sensation value is determined using the ratio of (a) the absolute value of the difference between the average luminance values, and (b) the minimum of the average luminance values of the current and prior picture blocks. Otherwise, the incremental visual sensation value is determined using the ratio of (a) the absolute value of the difference, and (b) the dark scene threshold. The method may be optimized by adjusting the block size based on the relative amount of motion and the current picture type.

Title: Impact type flow meter
Inventor: SATAKE SATORU
IPC: G01F1/30
Filed: 1997-12-22
Granted: 2000-01-01
Abstract: An impact type flow meter for a particulate material such as cereal comprises a supply device for dropping the particulate material, an inclined load detection plate for receiving the dropped particulate material, and a load detector for detecting a load of the particulate material exerted to the load detection plate. A bottom surface of the supply device is inclined at substantially the same degree with the load detection plate, and has at its lower end with a supply opening for dropping the particulate material onto the load detection plate. The bottom surface serves to guide the particulate material to the load detection plate at substantially the same inclination therewith. Thus, the flow meter has a buffer device for softening a dropping impact of the particulate material integrally incorporated in the particulate material supply device, and accordingly, the height is low and the whole apparatus is compact. The particulate material impinges upon the bottom surface of the supply device, diverges widthwise thereof and reaches the supply opening. Accordingly, the direction and position of dropping of the particulate material onto the load detection plate are fixed. Further, the flow-down speed of the particulate material is lessened, unevenness of the speed is averaged or uniformed, thereby the flow meter is high in measurement accuracy.

Title: R-2R bipolar and unipolar multiplication digital/analog converter (DAC)
Inventor: GAU SHIUE-WU
IPC: H03M1/66
Filed: 1998-02-17
Granted: 2000-02-21
Abstract: A multiplication DAC comprises a R-2R converter and an operation amplifier. The DAC operates in a unipolar or a bipolar mode by selecting a gain and compensating the voltage of an operation amplifier. The compensation voltage of zero voltage or the half voltage of a reference voltage is connected to a set of switches for determining the multiplication DAC being operated in unipolar or bipolar mode. The number of transistor switches is used to determine the current from the R-2R ladder network to the output terminal. The arrangement of the magnitude of the switches is used to generate a switch resistance that is a multiple of two. Such that the equivalent resistance of a ladder network can be reduced to a simple form comparable to a feedback resistance. The selected feedback generates an output having a gain 1X or gain 2X according to the unipolar and bipolar configuration.

Title: Method and apparatus for self-doping negative and positive electrodes for silicon solar cells and other devices
Inventor: MEIER DANIEL L
IPC: H01L31/068
Filed: 1998-06-15
Granted: 2001-01-11
Abstract: A self-doping electrode to silicon is formed primarily from a metal (major component) which forms a eutectic with silicon. A p-type dopant (for a positive electrode) or an n-type dopant (for a negative electrode) is alloyed with the major component. The alloy of major component and dopant is applied to a silicon substrate. Once applied, the alloy and substrate are heated to a temperature above the major component-silicon eutectic temperature such that the major component liquefies more than a eutectic proportion of the silicon substrate. The temperature is then decreased towards the eutectic temperature permitting molten silicon to reform through liquid-phase epitaxy and while so doing incorporate dopant atoms into its regrown lattice. Once the temperature drops below the major component-silicon eutectic temperature the silicon, which has not already regrown into the lattice, forms a solid-phase alloy with the major component and the remaining unused dopant. This alloy of major component, silicon and unused dopant is the final contact material. Alternatively, a self-doping electrode may be formed from an unalloyed metal applied to a silicon substrate. The metal and substrate are heated to a temperature above the metal-silicon eutectic temperature in an ambient gas into which a source of vaporized dopant atoms has been introduced. Dopant atoms in the ambient gas are absorbed by the molten mixture of metal-silicon to a much greater extent than they are absorbed by the solid silicon substrate surfaces. The temperature is then decreased to below the metal-silicon eutectic temperature. During this temperature decrease, the doped regrown silicon layer and the metal-silicon alloy final contact material are created in the same process as described above.

Title: Processes for preparing citrate esters
Inventor: FRAPPIER EDWARD P
IPC: C07C67/08
Filed: 1998-08-07
Granted: 2002-09-11
Abstract: Described are processes for producing citrate esters in an economic fashion. Esters are prepared by esterification of a citric acid-containing fermentation broth having been treated to remove cations and optionally other impurities, but containing sugar(s). Esters are also prepared by reacting an impure aqueous citric acid source with an alcohol to provide a heterogeneous aqueous/organic reacted mixture, wherein the organic phase contains the ester and the aqueous phase retains water-soluble impurities. A liquid phase separation is then used to separate the organic and aqueous phases, conveniently separating the impurities from the product and avoiding the energy-intensive distillation of water from the reaction medium.
